ffs, making a 40bb river call to "get information" is horrible. The chance that we are going to be able to make this back reliably based on this information is fairly low. Make the profitable play and don't come up with nonsensical stories to justify it.

If have no info I would 4 bet here. If he shoves I would probs call and take a note, quite often I get shoved from something like JA in this situation

It's not the worst spot to call. There are ton of worse info call spots, where we just want to see our opponents hand.
This is pokerstars, so you may be right. We might never see this opponent again. But if we were playing on iPoker, where we play same opponents day-to-day, we could get an important read on our opponent and can adjust for him later on.

This.

Turn should be a fold imo. I wouldn't be able to fold flop.

Calling for info at 25nl here is piss poor. There's no way you play enough hands with him to make it profitable for that info, and even if you did, I am not sure you would even use the info effectively or correctly.

That's the worst of all 3 options.

Yes that is true, you can probably piss your money away faster somewhere else. That doesn't make this reasoning close to good here.

The thing is, very often they'll give up with their bluffs and when they do, hero doesn't always just check it down. You need to take into consideration these scenarios as well.

When we face a 3 barrel, it's going to be a set quite often but probably not enough for us to fold on that particular river with these odds.

honestly, I strongly feel that the people that call down here and are able to rationalize it, are way too caught up in theory and don't play much at these stakes. Or they're really stubborn and/or biased.

So basically this same hand came up today. I floated and jammed my gutter+over ott. Cause, ya know, he was making a move its so dry right? And I had a "he makes moves"
read too! He had a set. Obviously.

I think there is two options in this spot. 1) Fold turn. 2). Calldown.

I may prefer to fold turn if vil is good and thinkable. If so, here is a causes to raise this flop with monsters:

1) The pot is very small. The big hand like set needs to stacks off villain KK. So raise, make pot huge.
2) He know that if he call flop and raise turn, we fold our overpairs definitely MORE bit of times. That way flop raise much more good than turn raise.

Another cause to fold:
On microlimits, when somebody represents very narrow range, he still had what he represents, especially on turn and river. Does villain may bluff here? How often? If bluff frequency tends to zero, than he really had a set.

But if villain is one of the many many players that not aggressive at all and plays huge hands like "trap all others" style, call-call-telephone, than I not fold that.

If I incorrect, please point me why.

You're good enough to realise that this isn't particularly relevant.

the question is how long your willing to repeat that to yourself.

I think this is exactly the question. this is really one of the best boards to check raise bluff, since hero will cbet it with 100% and it is unlikely to hit him.
but you don't want to get carried away and 60/40 value/bluff seems reasonable

good candidates are as you said 67s or 56s with the backdoor. I also like AQs with the backdoors if that's the strongest hand that doesn't 3 bet pre.
I also like 54s with the backdoor, which is the only draw on this board (and which in this hand got there.) I also think the bluff is one and done unimproved.
KK has 45% of the equity against this range +sets
